Hüftmoment nach transfemoraler Amputation - isometrisches und auxotonisches Hüftmoment bei Amputierten und Nicht-Amputierten

Zusammenfassung: The presented results allow a good assessment of muscle changes associated with an amputation its late effects. The comparison of isometric and auxotonic measurements shows which hip moments occur during gait, and which isometric maximums are possible.

Vergleich der maximalen isometrischen Hüft- und Kniemomente bei transtibial und transfemoral Amputierten während des Gangzyklus

Zusammenfassung: Maximum isometric moments of transtibial (TT) and transfemoral (TF) amputees were tested at the residual limb hip and knee. Compared to controls, TF showed hip strength deficits in all motion directions while TT had knee and hip strength deficits in all directions but in hip adduction and extension.

Besseres Gangbild und verringerter Energieaufwand durch osseointegrierte transfemorale Prothesen - Ergebnisse der OPRA Studie

Zusammenfassung: This prospective study on 20 patients treated with osseointegrated transfemoral prostheses show decreased energy cost and increased walking habits at 2-years follow-up as compared to the preoperative situation when using conventional socket prostheses.

Instrumentierte Bewegungsanalyse und transtibiale Prothesen - eine systematische Übersichtsarbeit

Zusammenfassung: A systematic review was conducted to critically evaluate methods used during three dimensional motion analysis of trans-tibial amputees. Presented is a critical review of the level of evidence, quality of research design, and summary of dependent and independent variables utilized by researchers.

Stabilitätsparameter - unversehrte und prothetische Gliedmaßen

Zusammenfassung: Plantar pressure data were collected while unilateral transtibial prosthesis users performed six walking tasks. Six dynamic stability parameters were extracted for each limb. The intact limb compensated for instability, enhancing stability during stance-phase on the prosthetic side.

Kinematische Messung am Knie mit einem magnetischen Inertialsensor bei Oberschenkelamputierten während des Gehens im realen Umfeld

Zusammenfassung: Evaluation of the accuracy of Inertial and Magnetic Measurement Units when measuring prosthetic knee kinematics was presented. Furthermore, a new kinematic coupling method to improve the accuracy and to correctly represent the kinematics of a C-Leg prosthetic knee was tested.

CAA - Computergestütztes Ausrichten - eine neue Methode des elektronischen Vermessens für passgenauere Beinprothesen anhand objektiver Kriterien

Zusammenfassung: A method has been developed to give component dependent bench alignment recommendations on a PC screen. For this, sensors in a knee prosthesis compute components and position of the static ground reaction force relative to the prosthesis. This method allows objective alignment without a gait-lab.
